使用列表循环的示例
#coding: utf-8
import multiprocessing
import time
def func(msg, msg2):
print "msg:", msg
time.sleep(3)
print "end"
print msg2
list = ["test", "hello", "hi", "good", "yes", "well"]
if __name__ == "__main__":
pool = multiprocessing.Pool(processes = 3)
for i in list:
msg = "hello"
pool.apply_async(func, (msg, i)) #维持执行的进程总数为processes，当一个进程执行完毕后会添加新的进程进去
print "Mark~ Mark~ Mark~~~~~~~~~~~~~~~~~~~~~~"
pool.close()
pool.join() #调用join之前，先调用close函数，否则会出错。执行完close后不会有新的进程加入到pool,join函数等待所有子进程结束
print "Sub-process(es) done."
